New Bike, tweaks & adjustments

Love my new Giant roadie. I'm close to 200 miles on it. Is there a rule of thumb to when and if I should take it back to the LBS from where I purchased to tighten cables, do minor adjustments, etc? It's shifting and braking fine, the fit is good too....no weird aches and pains on my body.

My LBS does offer 2 yearly check-ups & adjustments a year too, for the life of the bike.

thanks
